Structural strain extrapolation in nozzle-header connection
Structural strain extrapolation in nozzle-header connection
(OP)
In EN 13445-3, B.7.6, there is quadratic extrapolation described.
This extrapolation is used to get structural strain. The problem is that I get bigger value of strain using extrapolation than
don't use it. Have anyone experience with this extrapolation function.
Similar problem was described by one man. It concerned stress linearization. This linearization sometimes cause bigger stress than total stress.
